我现在正在ListActivity
尝试ListActivity
使用SharedPreferences
. 我在OnItemClickListener
with中添加了数据SharedPreferences
。我不知道如何ListActivity
使用ArrayList
. 下面是代码。
convertView.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
SharedPreferences pref = getContext().getSharedPreferences(
Constants.SHARED_PRED, 0);
Editor edit = pref.edit();
edit.putString("TITLE", getItem(position).title);
edit.putString("CHAR", getItem(position).character);
edit.putString("TOTAL", getItem(position).totalpages+"");
edit.putString("THUMB", getItem(position).thumbnail);
edit.putInt("CODE", getItem(position).code);
edit.commit();
System.out.println("Title >>>>>>" + getItem(position).title);
System.out.println("Character >>>>>>" + getItem(position).character);
System.out.println("Total >>>>>>" + getItem(position).totalpages);
System.out.println("thumb url >>>>>>" + getItem(position).thumbnail);
System.out.println("Code >>>>>>" + getItem(position).code);
Intent i = new Intent(getContext(), DetailPager.class);
i.putExtra("NPOS", position);
getContext().startActivity(i);
}
});
我的情况是我的应用程序中有两个活动。第一个 Activity 将ListActivity
使用启动SharedPreferences
。第二个活动将加载DetailPager.class
以代码编写的。我的问题是我不知道如何填充事件ListActivity
中未启动的内容OnClick
。
我的 ListActivity 类
private ListViewAdapter m_adapter;
public ArrayList<String> cat = new ArrayList<String>();

private SharedPreferences.Editor editor;
String title, character, thumbnail, totalPages;
int Code;

Uri thumbUri;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setTheme(android.R.style.Theme_Black_NoTitleBar);
getWindow().requestFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.myputet);
init_UI();
}
public void init_UI() {
preferences = getApplicationContext().getSharedPreferences(
Constants.SHARED_PRED, 0);
editor = preferences.edit();
title = preferences.getString("TITLE", "");
character = preferences.getString("CHAR", "");
thumbnail = preferences.getString("THUMB", "");
thumbUri = Uri.parse(thumbnail);
totalPages = preferences.getString("TOTAL", "");
Code = preferences.getInt("CODE", 0);
System.out.println("Getting Title " + title);
System.out.println("Getting character " + character);
System.out.println("Getting thumbnail " + thumbnail);
System.out.println("Getting thumbUri " + thumbUri);
System.out.println("Getting totalPages " + totalPages);
ListView lv = (ListView) findViewById(R.id.listview);
m_adapter = new ListViewAdapter(this, R.layout.myputet_item, cat);
lv.setAdapter(m_adapter);
}
private class ListViewAdapter extends ArrayAdapter<String> {
private ArrayList<String> items;
public ListViewAdapter(Context context, int textViewResourceId,
ArrayList<String> items) {
super(context, textViewResourceId, items);
this.items = items;

@Override

@Override
